l/ly present invention relates to improvements in shade holders, such asthose used for incandescent lamps, especially in out-ofdoors or otherexposed locations.

An object of the invention is to provide an eflicient means fordetachably securing a glass shade to the holder which will at the sametime seat the flanged rim or bead surrounding the mouth of the shadeagainst its seat in the holder. A further object is to provide anattaching means which will accomplish its object and at the same timeconstitute a yielding attachment which will avoid breaking the glassshade when it expands due to the heat of the contained lamp. Otherobjects will be apparent to those skilled in the art from the followingdescription.

The invention accordingly consists of the features of construction,combinations of elements and arrangements of parts as will beexemplified in the structure to be hereinafter described. Theaccompanying drawing serves to illustrate one preferred embodiment ofthe invention but without limiting the invention to all the detailsthereof except as same may be required by the appended claims in view ofthe prior art.

In the drawing, Fig. 1 is a longitudinal '2 mid-section through a shadeholder and shade having attaching means within my invention shown partlyin cross-section and partly in elevation; Fig. 2 is a partial view ofthe foregoing as looked at in the direction of the arrow designated 2 inFig. 1; and Fig. 3 is apartial view of Fig. 1 viewed in the direction ofthe arrow 3 in that figure.

Similar reference characters refer to similar parts throughout theseveral views.

Referring to the drawing, 1 is supposedly a metallic shade holder and 2is a glass shade co-operating therewith. lVhile these have the shapeshown in the drawing, this is purely for purposes of illustration sincethe invention is independent of shapes and sizes. It is also independentof the materials out of which the shade holder and shade are made exceptthat ordinarily, because the shade 2 must be transparent or translucent,it will be madeof a glass-like or some other more 1931.

or less fragile material. The shade holder will also ordinarily be madeconveniently of cast or spun metal. It will be understood that when theyparts are assembled, as in Fig. 1, they are supposeol'to house anincandescent lamp socket and lamp, the wires for which extend through ahole 3 in the top of the shade holder. However, for simplicity, theelectrical fixture has been omitted.

The shade holder 1 at its mouth is provided with an outwardlyextendingflange 4, and this flange is provided with a. rim 5 extending at rightangles thereto at its outer periphery. The glass shade 2 is providedwith an outwardly extending flanged rim or bead 6 at its mouth. Thisflanged mouth of the shade is receivable freely or loosely within therim of the shade holder and can be seated againsta gasket 7 locatedbetween it and the flange 4: of the shade holder.

At preferably several places spaced about the periphery, I provideattaching means, each comprising a strip of springy material such as astrip of spring brass 8. This is located in the space between the innerperiphery of the rim 5 of the holder and the edge of the flange 6 of theshade so that the length of the strip extends circumferentially aboutthe inner periphery of the rim. One end of the strip is riveted orotherwise secured to the rim 5, its other end being free or nonattachedto the rim. The width of the strip is considerably greater than thethickness'of the flange 6 so that the lower half of the strip extendsbelow or beyond it. Ascrewl) engages a threaded opening in the rim 5 atthe free end of the strip so that the end of the screw may be made toengage against the lower half or that portion of the strip which isbelow or beyond the flange of the shade. A look nut 10 engages the shankof the screw between the outside of the rim 5 and the screw-head.

Fig. 1 shows two of these attaching devices located 180 apart butobviously there may be three of them located 120 apart or a greaternumber if desired. To attach the shade, v the screws 9 will be screwedback to allow the spring strips 8 to lie adjacent the inner periphery ofthe rim, 5 and thereby permit 108 the flanged mouth of the shade to beinserted into the position shown in Fig. 1. The screws will then beadjusted inwardly into the positions shown in Fig. 1 with the resultthat the free portions of the spring strips will be forced inwardlyyieldingly against the periphery of the flange 6 of the shade and at thesame time the strips, especially towards their free end, will be twistedso as to force the flange of the shade yieldingly towards the flange ofthe shade holder; words, the spring strips have the combined action offorcing the shade yieldingly away from the rim 5 of the holder towardsone another and against the flange 4 of the holder. In both respects,the pressure is a yielding one and allows for expansion and contractionof the shade due to temperature changes. Thus, the shade is not onlysupported or suspended from the holder, but is forced firmly against thegasket 7 and the flange 4 of the shade holder so as to make asuiflciently dustand water-proof joint between them for all practicalpurposes.

As changes might be made in the embodiment above set forth withoutdeparting from the spirit and scope of the invention, it is to beunderstood that the matter hereinbefore set forth is to be interpretedas illustrative and not in a limiting sense.

What I claim is: V

1. A shade holder having at its month an outwardly extending flangeprovided with a transverse rim at its outer periphery; a glass shadehaving an outwardly extendlng flange at its mouth receivably looselywithin the rim of the holder against the flange thereof; and means forattaching shade and holder togeth, er comprising a strip of suitablematerial extending lengthwise of the inner periphery of the rim of theholder in the space between said rim and the flange of the shade, saidstrip being attached at one end to said rim and being free at its otherend, said strip being considerably wider than the thickness of theflange of the shade; and a screw operatively support-ed by the rim ofthe holder at the free end of the strip to bear against its portionwhich is below or beyond the flange of the shade.

2. The combination set forth in claim 1 further characterized by agasket of yielding material located between the flanges of the shade andholder respectively.

3. The combination set forth in claim 1 further characterized by alock-nut on the shank of the screw between its head and the outside ofthe rim of the holder.
